WINDOW-CLEANIN G DEVICE;

Application filed April 9,

This invention relates to an llIlPI'OWiECl win- .zIlOW cleaning deviceespecially adapted for attachment to thewindow frame to cooperatewiththe outside surfaces of thewindow panes, the device being such, inconstruction, as to automatically wipe such surfaces when the sashes aremoved up and down. i

My principal aim is to provide a simple and inexpensive device which canbe conveniently attached to the window frame and which will operate inthe automatic manner specified to obviate the necessity of exposing.ones self to danger by sitting in the window and leaning out in thecustomary manner.

The structure of .the device is such as to permit it to function assafety automatic window cleaning device, the same being adjust-ably madeto fit upon the window frame, and including a flexible wiping strip incontact with the outside surfaces of the window pane.

In the drawings Figure l is an outside elevational view of the ordinarywindow, showing the device attached to the frame in operative position.

Fig. 2 is a vertical section taken approximately on the line 22 of Fig.1.

Fig. 3 is an enlarged sectional and elevational View showing a close-upof the structure to represent more clearly the cooperation of thewiperwith the window pane.

Fig. 4 is a top plan view of Fig. 3.

Fig. 5 is a horizontal section through the window structure showingcertain of the parts in dotted lines.

Fig. 6 is a perspective view of one of the attaching brackets, and

Fig. 7 is a perspective view of the extensible or adjustable supportingmember, and

Fig. 8 is a. perspective view of the extensible or adj ust-ablesupporting member.

The supporting member last referred to, is generally designated by thenumeral 9. This member as shown better in Figs. 7 and 8 comprises asubstantially rectangular tube 10 and a slide 11, which is slidablymounted therein, the slide having an elongated slot to accommodatecertain bolts to be hereinafter more fully described.

These parts 10 and 11 are arranged in telescoping relation to cooperatewith the attaching bracket-s. Each bracket is designated by the numeral12 in general and as shown in Fig. 6 comprises a suitably shaped socket13 and attaching flanges 14. This bracket is 1928. Serial No. 268,530.

adapted to befirmly bolted upon the window Irame, as shown in Fig. 5.Thus, the two brackets when properly positioned serve to.

ings 20 at longitudinally spaced points for adjustable connection withthe bolts. The bolt, of course, passes through openings in the tubelOand then through the slot in the part 11. The plate 16 is formed withupstanding ears 21, with which corresponding ears on a retaining memberare pivoted. This retaining member includes a dove-tailed jaw portion22, cooperating withthe plate 16, to holda rubber wiper 23 in contactwith the window glass 24. The retainer includes a finger piece 25, and acooperating spring 26. Hence, the plate together with the retainer,forms a clamp for the rubber strip 23, which clamp is bodily adjustableon the supporting member 9.

This cleaner will serve to clean either the top or bottom window, andthis may be accomplished by appropriate adjustment of the a bottom plateadjustable wiper clamp. For cleaning the upper window, the clamp isadjusted outwardly, and for cleaning'the lower one, it is merely pushedin, to bring the wiper into contact with the glass of the lower window.In practice, the attaching brackets are permanently fastened to thewindow frame, at about the point indicated, or just where the upper andlower sashes meet, thereby permitting the device to be properly arrangedfor the dual cleaning operation specified.

Only one of the adjustable supporting devices and a'single wiper clampis absolutely essential, since the clamp can be adjusted to either halfof the window longitudinally ofthe supporting member, and the supportingmember can be bodily removed and transferred from window to window toclean the glass in the manner specified.

I desire to emphasize the adjustable clamp and to mention this. Wet feltis first inserted after it is adjusted for the top or bottom window.Then a strip of rubber to dry the window is employed. This is the reasonthat there are holes in the top so that it can be adjusted or placed inproper position for either the top or bottom Window.

It is thought that by considering the description in connection With thedrawings, a clearunderstanding of the invention and advantages will bequite clear to persons familiar With devices of this class. Therefore, amore lengthy description is regarded unnecessary. v I 7 Minor changescoming Witlnn thefield of invention claim-ed may be resorted to, ifdesired.

' outer ends removably arranged in the socket portion of said attachingbrackets, retaining bolts associated With the telescopically connectedsections for maintaining said sections in adjusted position, and Wipingmeans .embodying a Wiping element and retaining clamps for saidelements, said clamps being disposed at right angles to said supportingmember, and including portions extending across and intersecting thesupporting memher, and connected therewith by said retaining bolt.

2. A Window cleaning device of the class described comprising a pair ofattaching brackets, each including a socketed portion and attachingflanges, a longitudinally extensible supporting member occupying aposition between the brackets and adapted for horizontal disposition andincluding telescopically connected'sections Whose end por tions arereceivable in the socketed portions of said brackets, retaining boltsfor said sectrons, a wiping element disposed in spaced parallelism withrespect to supporting members, and adapted to contact the Window glass,and clamps for said element serving to adj ustably mount the element onthe supporting member, said clamps being disposed at right angles tosaid supporting member and each comprising a spring pressed retainerpivotally mounted on an apertured bottom plate, said bottom plate beingadjustably connected with the supp rting member through the medium ofthe aforesaid retaining bolt.

in testimony whereof I aflix my signature.
